Re: +1 Bob and Fred
Not a great example.
If both were running Windows, Bob popping round to Freds to sort it out might still result in Bob coking up Freds pc, depending on software version, drivers, and many other factors.
While, if Bob had even a marginally sentient I.Q. he'd be able to extrapolate from the commondesigns across both Ubuntu and Mint -> Control Panel -> Display -> Viola!
Personally, I prefer to depend on desktop-agnostic tools like xrandr
xrandr --output <monitor-name> --mode <resolution>
put in .xprofile is a quick, dirty solution..
Or do you imagine most people only have the I.Q. of a glass of water?
Frankly, if Bob and Fred were running Ubuntu and Mint respectively, they'd be spending most of their time in the pub arguing over which was the better distro/Desktop
And Frank, he sits looking on, feeling smug as he has a Mac,,,,.
